CAP FOR BOTTLES OR OTHER CONTAINERS.

Application filed January 1 1, 1924. Serial No. 685,531.

To all whom it may concem:

Be it known that I, LESLIE R. N. CAR- VALHO, a citizen of the UnitedStates, residing at Toledo, in the county of Lucas and State of Ohio,have invented new and useful Improvements in Caps for Bottles or OtherContainers, of which the following is a specification.

My invention relates to a cap or closure for bottles, jars or othercontainers. An object of the invention is to provide an improved form ofcap with means for sealing it on the container, together with meanspermitting the cap to be readily removed from the container andrepeatedly used as a closure for the container after the cap has beenoriginally removed.

In the accompanying drawings, which illustrate a preferred formof myinvention:

Figure l is a perspective view of the cap before it has been attached tothe container.

Figure 2 is a part sectional elevation of the cap and container with thecap sealed in osition on the container.

igure 3 is an elevation showing the cap applied to the container as atemporary.-

closure.

The cap or closure A may be madeof a single piece of sheet metal andcomprisesa top or cover portion 5 and a flange portion 6. The flange isscored or weakened along a line 7 extending circuinferentially of theflange. The score 7 preferably extends half or approximately half thecircumference of the cap and terminates at notches 8 and 9 formed in theflange.

When the cap is originally applied to the jar or other container B, thelower edge 10 of the flange portion 6 is turned inward beneath anannular shoulder 11 formed on the container, thereby sealing the cap onthe container. The holding flange 10 extends substantially the entirecircumference of the container. A ring or gasket 12 of rubber,composition or other suitable sealing material may be interposed betweenthe top 5 of the cap and the container to make a tight seal.

The score line 7 provides a removable rip strip 13 which .is preferablyformed at one end with a finger piece or tab 1 1. By grasping the tab14, the strip 13 may be ripped off the cap, permitting the latter to bereadily lifted from the container. After the cap has been thus removed,it may be quickly replaced on the container, thus serving as a temporaryclosure which, may be repeatedly applied until the contents of thecontainer have been used up. When the cap is thus replaced, that portionof the holding flange 10 which remains after the rip strip has beenremoved, extends approximately half way around the container and holdsthe cap from accidental displacement. The cap is preferably made ofsulficiently resilient material to permit it to be easily removed fromthe container after the strip 13 has been torn off without any permanentdistortion of the cap. This resiliency also causes the cap to snap intoposition when it is replaced on the container. The cap can thus beremoved or replaced without bending or distorting it beyond its elasticlimit. B changing the proportions of parts, as or example, the depth ofthe flange 6 or the length of the rip strip 13, the extent to which thecap must be sprung to remove or replace it, may be varied as desired.

Thus, by reducing the depth of the flange 6, and particularly thatportion above the line 7 the cap may be made to slip on or 0E thecontainer with the application of very little force and by springing thecap very slightly.

Modifications may be resorted to within the spirit and scope of myinvention.

What I claim is: p

1. A closure cap comprising a top portion and a dependingcircumferential flange portion, the latter formed With a score orweakened line extending lengthwise thereof approximately only half thecircumference of the flange and providing a removable strip, the scoreline being so positioned and arranged that when the strip is removed thedepth of the remaining flange along said half of the circumference issubstantially less than the depth of the other portion of the flange.

2. A, closure cap comprising a top porweakened line extending lengthwisethereof approximately only half the circumference ofthe flange andproviding a removable strip including all that portion of the flangebetween the score line and the bottom edge of the flange, and means atbothends of said strip to facilitate the tearing off thereof.

3. A closure cap comprising a top portion and a dependingcircumferential flange portion, the latter formed with a score orweakened line extending lengthwise thereof approximately only half ofthe cireumfer-. ence of the flange, said flange portion being cut ornotched from its bottom edge upward to the ends of the score line tofacilitate the removal of the strip beneath said score line.

4. A closure ca comprising a circular top portion and a depending flangeportion, said flange portion formed with a score line extendinglengthwise thereof through substantially half the circumference, therebyproviding a removable strip, the latter formed with a finger piece ortab at one. end, and means at the other end of the strip to facilitateits disconnection from the flange. A

5. The combination of a container, a cap therefor comprising a dependingflange surrounding the upper end of the container, the latter formedwith an annular shoulder, said cap having its lower edge inturned toform an annular holding strip or flange, and means to permit the readyremoval of a predetermined portion only of said holding strip, of suchextent that the cap may be removed from the container, the remainingortion of said strip after said predetermined portion is removed, beingof such extent that it serves as a means to hold the cap in positionwhen replaced on the contamer.

6. A closure piece or cap comprising. a circular cover portion and acircumferential flange extending downward from the' cover portion, saidflange being of greater depth at one side of the closure than the other,said deeper portion having at its lower edge an inwardly projectingportion serving as a means for holding the ca on a container theremaining portion 0 the flange being of a depth and extent to permit theremoval and replacin of the cap without bending or distorting it beyondits elastic limit.

7. A closure ca comprising a cover portion and a circum erential flangeportion extending downward therefrom, said flange portion being ofgreater depth throughout substantially half its circumference than theother half, said deeper portion having its lower edge turned inward toform a means for holding the cap on a container.-

8. The combination ofa container and a cap therefor, said cap comprisinga cover portion and a depending flange portion surrounding the upper endof the container, the latter forme with a circumferential shoulder, saidflange portion being turned inward along its lower edge to form aholding means surrounding the container and engaging said shoulder, saidflange portion of the cap formed with a score line extending lengthwisethereof for approximately halfthe circumference, the cap being formedwith notches extending from the --throughout one-half its circumferencethan the other half, said "deeper portion being formed with means toengage beneath said shoulder for holding the cap on the receptacle.

10. A closure cap for a container, said cap formed of a single piece ofresilient sheet metal and comprising a circular top I and acircumferential flange, the depth of said flange for approximately. halfthe circumference being materially less than the depth of the remainingportion, the lower edge of said remaining portion being inturned forengagement beneath a circumferential shoulder on the container, thenarrower portion of the flange being of a width to permit the cap to besprung onto and off the container without permanent distortion.

vl1. The combination of a container having an open circular top andacircumferential shoulder below said top, and a closure cap for thecontainer comprising a circular top and a depending circumferentialflange, the internal diameter of the flange being substantially the sameas the external diameter of the container between its top and saidshoulder, said flange comprising a comparatively narrow portionextending approximately one-half the circumference of the cap and awider portion completing the circumference, said wider portion beinginturned at its lower edge and en aging beneath said shoulder andholding t e cap on the ,container, the width of the narrow portion f theflange being such that the cap may be sprungoif or onto the containerwithout permanent distortion.

12. The combination of a container having an open circular top and acircumferential shoulder below said top, a closure cap for the containercomprising a circular top and a depending circumferential flange, theinternal diameter of the flange being substantiall the same as theexternal diameter of t e container between its top and said shoulder,said flange having itsllower edge inturne'd to engage beneath saidshoulder and thereby seal the cap on the container, the flange beingformed with a score line extending lengthwise thegeof forsubstantially-half the circumference of the cap and terminating atnotches formed in off the container without distortin or the flange andextending from the ends of bending the cap beyond its elastic limit. thescore downward to the lower edge of Si ned at Toledo, in the county ofLucas 1 the flange whereby a removable strip is proand fate of Ohio,this 8th day of January,
